IMPROVEMENT IN BURNING HYDR QCARBONS.

Specification forming part of Letters PatentNo.,132,440, dated October22, 1872.

To all whom it may concern:- i Be it known that we, J OSEPHUS CHANDLERand DAVID A. WRAY, both of Pioneer, in the county of Venango and Stateof Pennsylvania,

have invented a new anduseful Improvement in Burning Hydrocarbon s, ofwhich the following is a specification: v

This invention relates to that class of apparatus intended forburningh-ydrocarbons for the production of heat of greater or lessintensity in the various metallurgical operations of welding, brazing,heating, melting, deoxidizing, &c.; and it consists in the combinationof a steam or air jet, or both, a supply-' pipe for the admission ofhydrocarbon or'hydrocarbon vapors, a coil for superheating a secondsupply-pipe for the admission of hydro- I ondly, carbureting said fixedgas; and, thirdf,

ly, the function of a compound blow-pipe.

In the drawing .the figure represents our improved hydrocarbon-burner,portion thereof being in section the better to show the operation of ourdevice.

A is the pipe for the passage of air or steam, provided with astop-cock, a, and terminating in a jet or nozzle, J, said jet enteringthe enlargement of pipe F immediately beneath the delivery point of pipeB. B is a tube or pipe connecting with a hydrocarbon-reservoir, andprovided with a stop-cock, I), for regulating the supply of air orhydrocarbon. This pipe delivers the hydrocarbon or. hydrocarbon va-.

, por into the enlarged portion of pipe F, from whence it is impelledforward into superheater 0 by the jet enteringv from f. The pipe'F.decreases slightly in diameter, and is coiled Q to form superheaterO.Thiscoil may be inclosed' within a fire-chamberseparate fromor" in thesame furnace where the metallurgical operations are carried on. Afterleaving the coil or superheater O the pipe terminates in a jet ornozzle, g, which enters the enlarged portion of pipe G beneath andsurrounding the delivery point of pipe D. D is a pipe leading to asecond hydrocarbon-reservoir, and is provided with a stop-cock, d, tocontrol the flo vs ,of liquid or vapor. The pipe G terminates m a joint,0, which connects it with pipe E, and a second joint, 6, connects pipe Ewith p pe or nozzle H, the several connections formlng a universaljoint, whereby the gas can be d1 rected to and burned at any pointdesired.

- -'-"-:W h'en liquid hydrocarbon is used it is fed through pipes B andD (the flow being con;

trolled by stop-cocks b and d) intothe enlargedportions of F and G,where it 1s vaporized by. the jets of air or steamand gas. In I thiscase the reservoir should be above the level of the apparatus; or other.means should I be provided for'securinga steady flow 0f the hydrocarbon.

When a hydrocarbon vapor is used the vessels or reservoirs should bemade of iron or other suitable metal, and arranged withheating-compartments, the vapors generated being conducted into pipes Band D, and'from thence taking the same direction and going through, 1

a similar process to that employed when the liquid is used.

The operation of the device is thus described A jet of steam is admittedinto pipe A and passes through nozzle f into pipe F, carrying with'itthevapor or vaporizing the liquid hy-,

drocarbon admitted through pipe B. The gas thus generated passes intothe superheater or coil ,O,,. Where it is subjected to heat and be;comes a fixed gas. This fixed gas, as it issues from nozzle 9, meets anew portion of hydrocarbon-vapor or liquid, which it at once seizes uponand converts-into a gaseous or vaporous state, itself becomingsurcharged or carbureted. The gas then flows through pipe G to nozzle H,and is burned.

Inth above statement of operation whenever th'eivord steam is used airor oxygen may be substituted, asthe jet entering the pipe A maybeeitherair, steam, or oxygen, (gen eratedby'any of thewell-knownprocesses,) or of 1 two or more combined. When a great amount 1 of heatis required a number of jets are co1nblnedzz p v Having thus clearlydescribed our invention, what we claimie- 1. The process hereindescribed for generating and ee bn et g xed gas or chmpound blow-pipesand. similar apparatus.

2. The combination of the steam a r heir jet, the hydrocarbonjet, andthe' super-heater, as and for the purpose herein set forth. i

' 3. The ooinbinationof an air or steam jet,

a. hydrocarbon-jet, a super-heater, a. earbureting or second hydrocarbonjet, and a nnivergel Intestiihony that we clairn the foregoing we have hreimto fii nefl r names t i-ie 17th sla of May, 1872.
